The building sector accumulates approximately a third of the final ENERGY consumption. Consequently, the improvement of the ENERGY efficiency in buildings has become an essential ins trument in the ENERGY policies to ensure the ENERGY supply in the mid to long term moreover is the mos t cos t-effective s trategy available for reducing carbon dioxide emissions This paper is s tudying the main objectives for an effective sus tainable building taking into account the environmental sus tainability aspect, where it has introduced the main principles for developing building concept and the governor concepts for this development for forming sus tainable building skins, also it is focusing on the different techniques in terms of natural ventilation, shading techniques, and ENERGY CONSERVATION and its role in enhancing the internal environment. The main objective of the paper is to investigate the impact of different ventilation strategies that can be implemented in new and exis ting buildings in hot climates So that it can reduce the amount of ENERGY needed for building and sustainability in this climate.

Considering that a significant portion of the share of ENERGY consumption among consumer sectors is in the home and commercial sectors and this share is still increasing, there is a need for research in ENERGY consumption management and evaluation of effective indicators in the building industry. Building the country is vital to optimizing ENERGY consumption. One of the most appropriate ways to optimize fuel consumption in the building and housing sector is the implementation of zero ENERGY buildings which is considered as the main solution in the world. In this research, after analyzing the population and statistical sample, data were collected to evaluate effective criteria and options related to ENERGY consumption management. First, fuzzy Delphi method was used to evaluate the sub-criteria and select the main options of each. At first level the criterion is discussed and at the second level the data analysis and research model is analyzed through paired comparisons using fuzzy hierarchical analysis technique. Finally, the most important indicators and criteria are obtained using fuzzy hierarchical analysis. According to the research findings, among the ENERGY consumption optimization management indices investigated by the FAHP method, the economic, construction and utilities indices with 0. 333, 0. 201 and 0. 176 have the highest management priority, respectively. ENERGY-efficient optimization has a zero-ENERGY building approach.
